A further object is to provide simple and ctiicient means for throwing the inking roller out of position to contact with the face of the type or printing Wheels, together with means for securing it in such position, or in contacting position, as desired, during the stamping operation.

The invention will lii'st be hereinafter more particularly described with reference to the accompanying drawings, which are to be taken as a part of this specification, and then pointed out in the claims at the end of the description.

porting frame a reciprocating Vplunger proa printing wheel frame which is vertically movable therewith and in which aierevolu bly supported printing Wheels of ordinary construction, with the usual means foroper ating the saine, all of which parts are of linoivn construction and need not he spccitiq cally described.

ln' said drawings, in which the saine reference letters aroused to` denote correspond ing parts in different views, thc letterA denotes the main supporting fiaine, B the plunger and C the printing wheel frame, over which lf preferablyplace a shield D, having front and rear apro1ililie members, for a purposo hereinafter mentioned.

The inner sides or confronting surfaces of the legs of the supporting frame have vertical grooves therein to receive projections or studs@ on the printing Wheelfranie which linking reservoir F, also a roller Gr, for spreadingthe ink evenly on the irieriphcry of the inking roller I; said reservoir being adaptedl to its application toa dating machine being kinds of'inachines, for example, numbering machines, check writing machines, printing The machine shown has mounted onV its sup* vided with a suitable handle, and carrying proti'iule through openings inside plates of an oscillating frantic E which carries `the fluid ing reseivoir,` and an inking or ink dcliverdistribute ink` upon the spreading roller, which in turn delivers ink to the inking roller.

Said side plates have pivoted `thereto on the inner sides thereof oscillatory or swinging `levers H, of the form shown in Fig. 7,

in which the shafts of the spreading and ink ing rollers havetheir hearings; the ends of said shafts protruding through slightly elongated openings(il and Il, respectively iii-said side plates.

ingt '.t'eservoiif.

The spreading rolleris in peripheral contact with-said inking roller and with the distributing or feeding surface of the fluid inl;-

The spreading roller is of nit-types, :telt another sott and absorbent :iiiateral while 'the inking rollei is preferably of rubber.

The levers H are pivotally supported on the inner sides of the side plates of the oscillating frame E', and are each forked or bifurcated at the outer end While the other endsthereof carry inwardly projecting studs or pins L to each of which is secured one end of a coiled or other suitable spring h1, the other end of which is secured to a transverse rod or bar h2 connecting the side plates of the oscillating frame at the lower ends thereof7 so as to adapt said springs to actuate the swinging levers so to hold the inking roller normally in position to contact with the face of the type or printing wheels when lowered by the oscillating frame into contacting position7 and hold it in such position until thrown out of normal position by cam-actuated means carried by the oscillating frame and engaging the forked ends of said swinging levers; said means comprising a rod M fitted in alined openings in the side plates of the oscillating frame E and provided at one end with an operating lever m and having fixed thereon eccentric disks or cams m1 which are fitted in the forks or bifurcated ends of the swinging levers so that when the camcarrying rod M is turned in one direction said Ycams will actuate said swinging levers so Vas to throw the inking roller into position to prevent contact thereof with the face of the type or printing Wheels when the oscillating frame is lowered and hold it in such position. On the reverse movement of said Cain-carrying rod,the inking roller will be thrown into position to contact with the face of the type or registering wheels when the oscillating frame is lowered and maintained in such position until the cam-carrying rod is again rotated to throw the inking i'oller out of contacting position; V

The operating handle m has its fiee end turned inwardly as at m2 to engage alternately depressions m3 and mL on the outer 'side of the adjacent side plate of the oscillating frame E, so as to hold the inking ioller in either contacting or non-contacting position. Y

They side plates of the oscillating frame are eccentrically fulcrumed upon the legs a of the supporting frame A by means of a vshiftingfulcruin consisting of pins or screws c screwed into interiorly threaded openings therefor in said legs and protruding into elongated slots 01 in said side plates, so that .when the plunger is lowered its downward thereby raising the fluid inking reservoir and throwing the inking roller out of contact with the face of the type or printing wheels.

The hiking reservoir F is preferably composed of telescopically connected inner and outer tubulai members f and f1, but they may be polygonal in cross-sectitn` and each is open at one end and closed at the. other end, said closed end of one or both members having a. ti'lling aperture therein which is provided with a removable stopper for closing said filling aperture. 'llach member has minute orifices or pin-holes therein arranged normally in separated relation but adapted to be brought into registering position by adjusting or moving one of said members in the line of its axis. Each tubular member of the inking reservoir is provided at the closed end thereof with a radially projectinglr tlange f3, which preferably annular in formand between said flanges is secured a cylindrical body F1 of felt or other absorbent material surrounding the reservoir, said body being preferably composed of a series of rings arranged side by side and having annular metal plates on t-he outer sides of the outer rings connected by a bolt or bolts passing through the series of rings and securing them together so that they will rotate in unison.

To prevent rotary movement of the cylindiical body 0r feeder independently of the tubular members of the ink reservoir a nail or other fastening device f is inserted through the iange f3 on the outer member and through the adjacent plate f* into said body.

To rotate the ink reservoir theI closed end of the outer member thereof may be formed with a reduced end. port-ion on which is tixed a gear wheel N beside which is aratchet wheel n secured thereto and to the outer member of the ink reservoir by means of a screw nl so as to cause said parts to rotate in unison; the screw nl being concealed and held in place behinda flange on the end of the stopper f2. The pinion N1 is Iixed on one end of the spreading roll shaft. and meshes with the gear wheel N and with a gear wheel t) on one end of the shaft of the. inking roller l so that when rotary movement imparted to the gear wheel N and through it to the ink reservoir and feeder` the. spreading roll will be caused to rotate, in an opposite direction while the inking roller rotates in the same direction.

otary movelncnt is imparted to the described train ol gears by means of a paw] l) pivoted at one end on the supporting frame, A and having a tooth on the other end adapted to engage the teeth of the ratchet wheel n and rotate the gear wheel N and through it the inking and slpireading rollers when the free end of the oscillating frame moves downwardly7 said frame being,r adapted to Swing llll along curved `lines eccentric to the pivot-of the pawl P, anden the reverse movement said pawlwill slide freely over the inclined `teeth et the ratclietfor engagement with another tooth on the next downwardmovement of the oscillatingframe.

Means are provided at one end iotthe inl ingr reservoir for adjusting-and Securing the iluid containing member y" with the orifices therein in regietering- `position with the orilicee` in the outer member f1 and vice versa, euch means, in the form Shown, consisting)r of a lever R pivoted intermediate ite ends to a lug or bracket on the outer side ofthe adjacent side plate ot the oscillating` frame and havingy1 a forked `end engaging` a groove i' in a hiib-lil e end portion of the inner member ot the inliingr reservoir; a coiled or other suitable spring S being Secured` between the .side plate oit' the oscillating` `iiaine `and the tree eiid of the le ver R so as tti-normally torce said .iree end outwardly and lio-ld the inner `lluid containing member ol the `reservoir with its oriiicee in separated relation to the orilices iii the outer member f1.
